  • the present invention also relates to a drive mechanism (hereinafter referred to also as "chain hoist”) including such a chain guide.
  • chain hoist a drive mechanism including such a chain guide.
  • a pocket wheel is generally operatively fixed to said main shaft and a chain is operatively suspended about said pocket wheel.
  • the operating of this chain enables the manual raising and lowering of the door assembly. When the door descends very quickly, the chain turns, looses its tension and may be drawn outside the pockets of the chain pulley given the centrifugal force created by the rotation of the shaft.
  • the object of the present invention is to provide a chain guide (and/or a drive mechanism including the same) which, by virtue of its design and components, satisfies some of the above-mentioned needs and is thus an improvement over other related devices and/or methods known in the prior art.
  • the present invention is particularly advantageous in that it is intended to maintain a given chain of a chain hoist within the pockets of the chain pulley when the latter is turned excessively rapidly.
  • the present invention is also particularly advantageous in that it comprises a flexible band which is devised so as to be able to deform itself and/or allow the passage of certain knots or twists formed in the length of a given chain.
  • the chain guide according to the present invention is designed to be able to resist to certain impacts and/or deform itself, if need may be, as will be explained in greater details hereinbelow, and as will be better understood when referring to the accompanying drawings.

  • a garage door preferably requires to be counterbalanced in order to facilitate its opening and its closing.
  • the counterbalancing of a door is generally ensured by at least one torsional spring which is operatively mounted about the main shaft of the door assembly. It is possible to operatively add a chain hoist operatively connected to said shaft so as to enable to raise and lower the garage door, typically in a manual manner, when the use of a mechanical operator is not appropriate.
  • Manual chain hoists are typically used into many situations, namely: a) when a given door is very heavy and that it is very difficult to overcome the inertia of the counterbalancing springs when a person wants to open it; and b) when it is impossible for a person to completely raise a very high door.
  • chain hoists which differ one from the other by means of the type of components being used, the desired ratio and the utility sought out.

  • the substantially elongated body 13 comprises a longitudinal axis 47, and the middle section 33 of the connecting portion 17 and the open channels 31 of the chain receiving portions 15 are longitudinally aligned with respect to said longitudinal axis 47 of the substantially elongated body 13.

  • the flexible band i.e.
  • connecting portion 17) of the chain guide 1 may deform itself on one side or the other, depending on where is applied the pressure caused by the chain 5 which wants to come out from the pockets of the chain pulley (it is important to note that typically, in conventional systems, nothing retains the chain 5 within the pulley).
  • the chain guide 1 may comprise a support portion 51 extending between corresponding shoulders of the first and second chain receiving portions 15a,15b, as better shown in Figures 24-25 .
  • This support portion 51 could also comprise an orifice 53 for removably hooking the chain guide 1 via its support portion 51 onto a component of the chain hoist, particularly in the case of an "open" chain hoist (i.e. without a casing 11), as better shown in Figures 26-27 .

  • the faster a given chain turns about a chain pulley the greater the risk of provoking resulting vibrations in the corresponding internal components of the chain hoist.
  • noise is very often amplified by the resonance of the casing (typically, a metallic casing) created often by a closed chain hoist.
